The young physiotherapist had been flown to Singapore for treatment late Wednesday.

"The girl reached Singapore at 5.30 in the morning. According to the report I received an hour ago, she has been admitted to the hospital and is stable," Azad told reporters here.

The grievously injured victim was admitted on Thursday morning to the Mount Elizabeth Hospital's intensive care unit in Singapore in an extremely critical condition, a hospital spokesperson said.

"The patient arrived at Mount Elizabeth Hospital's Intensive Care Unit this morning in an extremely critical condition," the spokesperson said.

"She is being examined and the hospital is working with the Indian High Commission. We request that the privacy of the patient and family be respected," the spokesperson said.

The decision to shift the girl was taken at the highest level of the Indian government.

On December 16, the girl was gangraped and brutally assaulted in a moving bus in the national capital and was undergoing treatment at a hospital in Delhi.

The girl, battling for life for the past 10 days at Safdarjung hospital in New Delhi, remained on ventilator support during most part of her treatment in Delhi.

Following the incident which shocked the nation and triggered widespread protests, a Commission of Inquiry headed by a former Delhi High court judge to go into the gangrape incident was set up on Wednesday by the Indian government.
